The girl's name was GLUTTONY, and like her other brothers and sisters, she was created for the sole purpose of being a weapon of mass destruction and evil. These "SINS," as they were called, received abilities far beyond their understanding, and were experimented on relentlessly, until they could no longer feel any pain.
They were powerful, but if they fell out of line, the ANGEL had ways to make them suffer, and would show no mercy.
Although this girl was the youngest of them all, she would be no exception, for she was the SEVENTH.
When the six kids were taken, they were just infants. But when the needles are sterilized, they know something bad was about to happen. Years later, their powers were fully mastered, and the thoughts of escaping creeped into their minds. Oblivious to the limited amount of others in the facility, they try their first escape, though that fails once one gets captured. As they see new faces and explore outside their domain, they struggle to escape from the twisted minds of the adults. They'll all make it out alive... Right..?
